A photoluminescence polymer was prepared using acrylamide as a monomer, a large excess of ethyleneglycol dimethacrylate as the cross-linking agent, and curcumin as a fluorescence additive. The polymer was ground into powder and screened in order to get even powder, whose diameter was from 40 to 75 microm. The emission spectra of curcumin in solid powder polymer show a strong blue shift compared with that of curcumin in C2H5OH solution. Meanwhile, rhodamine 6G, tetraiodofluorescein and phloxin have the same phenomenon of blue shift. Based on these facts, we speculate that the mechanism is probably singlemolecular luminescence because of the limit effect in three dimension space of the polymer. The molecule fluorescence peak was also depending on its environment because the surrounding electron field affected the molecule luminescence in polymer.
